Mooney-Shiner

Thank you! It seems that all of the shieldings are to be grounded at the panel. Does anyone have a photo what this grounding should look like? Is there a bus to ground everything?

Thank you for all the useful information on the thread. I’m doing a dry fit right now without the trim. But I’m not sure if I like how the bolt and nut is rubbing against the window. What would you guys recommend?

Vance, thank you for such an in-depth explanation. I tracked down the speaker issue, and it turned out to be an accidentally disconnected spade connector on the speaker. After reconnecting it, the speaker works exactly as it did before. To answer your points: the shielding on the wire is used on the LO side of the speaker and is tied into the panel/frame ground, while the main conductor is used as the HI lead running straight back to the audio panel. Even though this setup has technically been working, it’s clearly not the correct way to wire it, so I’ll need to redo the speaker wiring properly. Thank you for catching that. What type of wire would you recommend for the rewire? And thanks again to you and everyone here for the phenomenal support.

Sorry, I should have been more specific. The speaker is completely silent and not working right now. I have pretty good continuity for the High side, but very high resistance(with Master on) on the Low side. I also measured the Low side to the Low side pin return pin on the tray, but I noticed that the Low side pin is connected to the frame (AKA ground). The resistance between the tray Low pin and the ground is 0.8 Ohm (acceptable). The speaker is not energized when only Master is turned on. It is energized when Avionics switch is turned on, which turns on the Radio/AudioPanel/GPS/etc. But the AudioPanel Speaker Low side pin is connected to the same ground (airframe) that Master uses. Here is the pinout for the Audio :

Hey, fellows, I'm trying to understand my electrical gremlins to get my speaker to work right. I was testing electric continuity from tray pin to the speaker wire. Good continuity on Speaker HI side (+) and high resistance on the Speaker LO (-) side. I started measuring and shot this video. Any help is appreciated.

How much for the belly strobe? Mine still working, but I thought about getting a spare one just in case.

Thats pretty cool. For whatever reason, My 67F POH doesn't have sea level performance table. It starts at 2500 MSL.

I wonder if there is a way to install Accutrack II device on my 67F that has Brittain wing leveler vac system and TC100EVS Autopilot Gyro? Any videos on that?

Hi, everyone! Does anyone know if there are patterns available for cutting and sewing wing and tail covers for our Mooneys? I’d rather not try to reinvent the wheel by starting completely from scratch if there are templates or designs already out there. Thank you!

Just bringing this thread back from the dead: Since I’ve been based at a coastal Florida airport (beautiful spot, but hot and humid) with my Mooney since 2020, I made a habit of replacing corroded or worn fasteners with stainless steel ones. The line for hangars are decade long and I'm on the outside tiedown. But the more I’ve read on this, the more I realize that cadmium-plated screws are actually less noble than stainless and closer to aluminum on the galvanic scale. Counterintuitive as it seems, that means cad-plated screws can promote less corrosion than stainless when installed in aluminum. Sure enough, I started noticing filiform corrosion forming around my fuel tank access panel after swapping the original screws for stainless steel ones. Does anyone have an experience with this?

For the sake of posterity, I've got a reply from Hartzell with the IPC for the H-1 governor. Looks like Hartzell 2024 IPC calls for B1104, AKA MS9144-01.

Thank you. Luckily, I'm not dual mag. Just regular A1A with two split mags.

Thank you for all of the great help, guys. We will re-install the proper hardware on it. Also based on the discussion above the proper gasket from the governor to the adapter is 72053 or NOT MS9144-01 or NOT 69551 type (IO-360 IPC is confusing on this)?

Another view of my governor mating surface. We are planning to attach the gopro and do the ground run to see where is the leak. After that, we will likely rebed the governor with new set of washers and nuts.

Thank you. I saw this page, but got confused (crayon eating Marine here). I have #16 adapter assy as shown on the schematic. My H-1 mounts to to this adapter assy. Does this mean that GOV mounts to the adapter assy using #29 gasket PN 72053? The schematic shows #29 going to different setup. Here's not the best photo that I have of my GOV at home.
